Summary: Storage tab no longer updates after main frame navigation. Steps to Reproduce: 1. Inspect any page with cookies 2. Open Storage tab 3. Reload inspected page => Storage tab content view and navigation sidebar are empty This regressed in https://trac.webkit.org/changeset/236766. Note: Prior to the patch that caused the regression, StorageSidebarPanel only listened for StorageManager.Event.Cleared (now DOMStorageManager). Cleared events from other managers were ignored. A main frame navigation causes all these managers to now broadcast Cleared events, which are interleaved with events for their respective storage objects being added. This causes the content tree in the Storage sidebar panel to get thrashed during frame navigation.
